| Outline of Final Research Achievements |
We investigated the serial change of the side branch ostium jailed by drug eluting stent in the coronary artery bifurcation lesion by the three-dimensional optical coherence tomography. The response of the remote phase is different depending on the complexity of the stent covering configuration. The side branch ostial area decreased at the remote period when the stent covering configuration was complicated. In the case of side branch dilatation, when the number of remaining struts was large, the ostial areas often decreased in the remote period. The frequency of the remaining strut after side branch dilatation was higher when the longitudinal stent link was present at the carina. We developed a dedicated bioresorbable scaffold for the bifurcation lesion and evaluate them in the simulated phantom vessel. It was observed the cutting of the longitudinal link of the stent and that the side branch ostium was opened widely.
